I want to run update query to update PercentAvailability column value 0 to 100 between specified date period in my case 2012-10-28 03:31:01 to 2012-10-28 08:31:01. see following picture.

How do i run query to update above data between specified date?
Note: I have many ApplicationID which has this issue so how could i run query against all ApplicationID, I believe we need to run JOIN syntax but it would be good if you give some short of hint.
Use this query
or if you want to update the same thing only for a specific
ApplicationIDthen door for multiple
ApplicationIDdoor for a big number or
ApplicationIDyou could do a subquery
